The Florida Department of Law Enforcement is investigating a police shooting in Brevard County where officers opened fire and wounded a man suspected of holding up a Walgreens at gunpoint Tuesday night.

Palm Bay Police said a masked man — identified this morning as Kenneth Kirwan Jr., 20, of West Melbourne — terrorized customers inside the business at 1160 Malabar Road about 11 p.m. and held a pharmacist at gunpoint during the suspected robbery.

Kirwan is in critical condition.

The suspect tried to flee and shots were fired, striking the man, said Yvonne Martinez, a police spokeswoman.

Martinez said the department will not release the name of the officer involved in the shooting until "proper protocols have been implemented."

No one else was injured.

"Detectives are continuing the investigation into the armed robbery and felony charges are pending for the suspect,'' a statement from Martinez said this morning.
